Quality Siding Material, We Know What is Right For You

As of January 1, 2026, this falls under California's Wildland-Urban Interface Code (CWUIC, Title 24 Part 7) — the same rules that used to live in Chapter 7A, just relocated. Noncombustible materials qualify outright: James Hardie fiber cement (Class A) and metal siding (ASTM E136) are both eligible statewide. Real wood is combustible (Class B/C) unless it's a specific fire-retardant-treated product with a current OSFM listing. Engineered wood (LP) and vinyl are not eligible as a standalone wall covering in mapped fire hazard zones. ACRE's Shiplap profile specifically holds an OSFM WUI listing as an ignition-resistant material — but that listing doesn't automatically extend to their other profiles. We verify the current listing before recommending anything for a fire-zone property; we don't assume.

Roughly, from cheapest to most expensive installed: vinyl ($3-8/sqft), engineered wood ($6-11/sqft), corrugated metal (~$4.50-8/sqft, standing seam runs closer to $9-15+), James Hardie ($8-15+/sqft), ACRE ($10-12+/sqft), and real wood ($15-25+/sqft) at the top. The cheapest option isn't always the best value once you factor in fire-zone eligibility, warranty coverage, and how often a material needs repainting or replacing.

A proper installation includes: removing the old siding, inspecting for dry rot and structural damage, installing a continuous house wrap moisture barrier, applying FortiFlash or Blueskin self-sealing membrane at all window and door openings, correct L-flashing at every horizontal transition, and finally installing the siding panels to the manufacturer's exact specifications — spacing, fastening pattern, and clearances — to preserve the product warranty. Most siding failures we get called out to fix trace back to a skipped step here, not the material itself.

Yes. Once the old siding is removed, we inspect every square foot of sheathing and framing for dry rot, moisture damage, and mold. Any damage is repaired before the new siding goes on — so your new exterior is built on a solid, healthy substrate. We document all findings and include repair costs in your estimate transparently.

We hold James Hardie Elite Contractor status and LP Certified Installer status — both are real, earned certifications. We also install ACRE, metal, and vinyl siding, matched to your property's needs.

Yes. Blyss backs every project with a labor warranty on top of the manufacturer's product warranty. We maintain undivided responsibility — one guarantee for both the materials and the installation, from one company. If something isn't right, we make it right.
